Abstract
The utility model discloses a kind of crucible bell for molten magnesium production, opening part in the middle part of crucible furnace upper cover is provided with scissor folding lid, described scissor folding lid is made up of two semicircle bells, the inner side of two semicircle bells is provided with heat-insulation layer, and one end of two semicircle bell homonymies is flexibly connected with described crucible furnace upper cover.Scissor folding lid of the present utility model, adds heat-insulation layer, reduces the heat exhaustion in liquid magnesium production process in the middle of folding upper cover; Folding upper cover is arranged to scissor symmetrical structure advantageously in folding, site operation personnel does not need frequently to hang bell, only needs console switch handle just can complete the switch of folding upper cover, increases work efficiency, and reduces labour intensity; Reduce liquid magnesium and the oxygen touch opportunity in air in crucible furnace simultaneously, thus reduce liquid magnesium scaling loss, reduce smart magnesium addition, the magnesia amount of raising liquid.
Description
Technical field
The utility model belongs to magnesium metal smelting technical field, relates to crucible furnace, is specifically related to a kind of crucible bell for molten magnesium production.
Background technology
At present for the crucible furnace of magnesium ingot melting refinement, in the production operation process of magnesium ingot melting refinement, magnesium ingot is not disposablely join in crucible furnace, but gradation adds in crucible furnace, need crucible furnace upper cover to hang out at every turn before adding magnesium ingot, again bell is winched on crucible furnace after adding and build.In this case, this bell not only can strengthen the thermal loss in liquid magnesium fusion process because of frequent handling, and large lid hangs out period, in crucible furnace, liquid magnesium bump contact makes the oxygen reaction in liquid magnesium and air generate magnesia to air, make to produce impurity in liquid magnesium, increase liquid magnesium scaling loss amount, also reduce smart magnesia amount simultaneously.Employee's execute-in-place is too frequent, inefficiency.
Utility model content
The utility model need frequently open crucible furnace upper cover, troublesome poeration to solve when molten magnesium is produced, and affects the problem of product quality, provides a kind of crucible bell for molten magnesium production.
In order to solve the problem, the utility model adopts following technical scheme:
A kind of crucible bell for molten magnesium production, comprise middle part and open crucible furnace upper cover cyclostomous, scissor folding lid is provided with above round mouth in the middle part of described crucible furnace upper cover, described scissor folding lid is made up of two semicircle bells, the inner side of two semicircle bells is provided with heat-insulation layer, and one end of two semicircle bells contacts and is flexibly connected with described crucible furnace upper cover.
One end that described two semicircle bells contact, each semicircle bell is connected with a turning set, the crucible furnace below two turning sets covers and is fixed with pin respectively, and two turning sets are corresponding to be respectively sleeved on respective pin.
The circular bell of described two halves is connected with switch knob respectively.
Scissor folding lid of the present utility model, adds heat-insulation layer, reduces the heat exhaustion in liquid magnesium production process in the middle of folding upper cover; Folding upper cover is arranged to scissor symmetrical structure advantageously in folding, site operation personnel does not need frequently to hang bell, only needs console switch handle just can complete the switch of folding upper cover, increases work efficiency, and reduces labour intensity; Reduce liquid magnesium and the oxygen touch opportunity in air in crucible furnace simultaneously, thus reduce liquid magnesium scaling loss, reduce smart magnesium addition, the magnesia amount of raising liquid.
Accompanying drawing explanation
Fig. 1. be structural representation of the present utility model;
Fig. 2. be top view of the present utility model.
Detailed description of the invention
As shown in Figure 1, 2, a kind of crucible bell for molten magnesium production, opening part in the middle part of crucible furnace upper cover is provided with scissor folding lid, described scissor folding lid is made up of two semicircle bells 6, the inner side of two semicircle bells is provided with heat-insulation layer 7, and one end of two semicircle bell homonymies is connected with a turning set 4 respectively, the crucible furnace below turning set covers and is fixed with pin 5, two turning sets respectively correspondence are enclosed within pin, and the circular bell of two halves is connected with switch knob 8 respectively.
Crucible 1 puts into crucible furnace body of heater 2 when melting magnesium ingot, be stamped the crucible furnace upper cover 3 of middle opening above, be provided with in scissor folding lid 6 above crucible furnace upper cover 3, scissor folding lid its form scissor symmetrical structure by two semicircle bells, realize the switching function of closing device upper cover by operating two switch knobs 8.Two fixing pins 5 are welded on crucible furnace upper cover 3, for playing fulcrum fixation to the folding of scissor folding lid; Two turning sets 4 are welded on one end of semicircle bell 6 homonymy respectively, play connection function to the folding of described scissor folding lid; Switch knob 8 is welded on the other end of semicircle bell 6 homonymy of two, scissor folding lid, for folding fast light during feeding operation; Heat-insulation layer 7 in the middle of the semicircle bell 6 of two, scissor folding lid, plays insulation effect to liquid magnesium in crucible furnace.In use, when adding magnesium ingot if do not needed, two upper covers are closed by switch knob by scissor folding lid, by switch knob, scissor folding lid is opened when needing to add magnesium ingot, flexible operation is convenient, do not need frequently to lift by crane crucible bell, and can be incubated liquid magnesium well, reduce the chance of liquid magnesium ingress of air thus reduce liquid magnesia, increasing liquid magnesium output.
Claims (2)
1. the crucible bell for molten magnesium production, comprise middle part and open crucible furnace upper cover cyclostomous, it is characterized in that: above the round mouth in the middle part of described crucible furnace upper cover, be provided with scissor folding lid, described scissor folding lid is made up of two semicircle bells, the inner side of two semicircle bells is provided with heat-insulation layer, one end of two semicircle bells contacts and is flexibly connected with described crucible furnace upper cover, one end that described two semicircle bells contact, each semicircle bell is connected with a turning set, crucible furnace below two turning sets covers and is fixed with pin respectively, two turning sets are corresponding to be respectively sleeved on respective pin.
2. a kind of crucible bell for molten magnesium production according to claim 1, is characterized in that: the circular bell of described two halves is connected with switch knob respectively.
